BACKGROUND

The present technology relates to a haptic-feedback presenting apparatus, a haptic-feedback presenting system, and a haptic-feedback presenting method presenting information to a user by a haptic feedback.

In recent years, instead of information transmission means in the past such as vision and audition, information transmission by a haptic feedback has been developed. For example, in Patent Literature 1, a haptic-feedback transmission apparatus for transmitting a solid object formed in virtual space to a user by the haptic feedback is disclosed.

Moreover, a technology reconstructing a predetermined environment as an object of information transmission has been developed. For example, in Patent Literature 2, an output control technology of environment information extracting characteristics in various environments in a remote place as environment information, and outputting the characteristics to a predetermined space equipment is disclosed.

Technical Problem

In Patent Literature 1, the solid object formed in the virtual space is assumed to have an object shape including a surface texture. Moreover, in Patent Literature 2, an environment technology is an image, sound, a wind direction, a wind speed, or the like. On the other hand, if it is possible that information mapped in space is presented without vision and audition, it will be convenient.

In view of the above-mentioned circumstances, it is an object of the present technology to provide a haptic-feedback presenting apparatus, a haptic-feedback presenting system, and a haptic-feedback presenting method capable of presenting information mapped in space without vision and audition.

According to the configuration, the haptic-feedback arithmetic part calculates the haptic feedback to be presented to the user depending on the determination result showing whether or not the mapping information included in the detection-target region (for example, scattered pollen count) is the threshold or more. Due to this, the user may grasp by the haptic feedback presented by the haptic-feedback presenting apparatus that the mapping information in the detection-target region is the threshold or more.

DETAILED DESCRIPTION Configuration of Haptic-feedback Presenting Apparatus

FIG. 1 is a perspective view showing a haptic-feedback presenting apparatus 100 according to the present embodiment. The haptic-feedback presenting apparatus 100 may be a mobile apparatus such as a smartphone, a tablet PC, or a head mount display capable of realizing a functional configuration described below. Hereinafter, the haptic-feedback presenting apparatus 100 will be a smartphone and be described.

As shown in FIG. 1, the haptic-feedback presenting apparatus 100 includes a display 110. Furthermore, the haptic-feedback presenting apparatus 100 may include a button and the like that are not shown.

FIG. 2 is a block diagram showing the functional configuration of the haptic-feedback presenting apparatus 100. As shown in FIG. 2, the haptic-feedback presenting apparatus 100 includes a mapping-information acquisition part 101, a position detection part 102, an attitude detection part 103, a region detection part 104, a haptic-feedback arithmetic part 105, and a haptic-feedback presenting part 106 as the functional configuration.

The mapping-information acquisition part 101 acquires mapping information. The mapping information is information related to a particular position in space or on a plane. FIG. 3 is an example of the mapping information, and shows a scattered pollen count on each spot at a specific time point.

Furthermore, examples of the mapping information include a density of an environment such as a radio wave intensity, rain, dust, radioactivity, an ultraviolet ray, an amount of solar radiation, and quantity of airflow, a density of a thing such as congestion in a train and a running position of a train, a density of human such as crowding of human, a place, line of sight, and conversation, a density of a feeling such as an upsurge, exaltation, and a calm, and the like.

As shown in FIG. 2, the mapping-information acquisition part 101 may acquire the mapping information from cloud information via a network, and may acquire the mapping information from an output from a sensor included in the haptic-feedback presenting apparatus 100. Furthermore, the mapping-information acquisition part 101 may also acquire the mapping information by various means. The mapping-information acquisition part 101 supplies the acquired mapping information to the region detection part 104.

The position detection part 102 detects a position of the haptic-feedback presenting apparatus 100. The position detection part 102 may detect the position of the haptic-feedback presenting apparatus 100 by using the GPS (Global Positioning System). Moreover, the position detection part 102 may also detect the position of the haptic-feedback presenting apparatus 100 by using Wi-Fi or the like. The position of the haptic-feedback presenting apparatus 100 may be a three-dimensional coordinate (for example, longitude, latitude, and height), and may also be a two-dimensional coordinate (for example, longitude and latitude). The position detection part 102 supplies the detected position of the haptic-feedback presenting apparatus 100 to the region detection part 104.

The attitude detection part 103 detects an attitude of the haptic-feedback presenting apparatus 100. The attitude detection part 103 may detect the attitude of the haptic-feedback presenting apparatus 100 by using an output from each of a geomagnetic sensor or an acceleration sensor. The attitude detection part 103 supplies the detected attitude of the haptic-feedback presenting apparatus 100 to the region detection part 104.

The region detection part 104 sets a detection-target region. FIG. 4 is a diagram schematically showing the detection-target region R. As shown in FIG. 4, the region detection part 104 may determine the inside of a circle having a radius ra, a center of which is the position P of the haptic-feedback presenting apparatus 100, as the detection-target region R. The position and the attitude of the haptic-feedback presenting apparatus 100 at a time point (t) are referred to as the attitude position (x,y,z,θ)(t).

The radius ra is not particularly limited, and a user may set the radius ra. Alternatively, the region detection part 104 may determine the radius ra depending on a type of the mapping information or the like. Moreover, the detection-target region R may not necessarily have a circular shape. Furthermore, the detection-target region R may not be a region in which the haptic-feedback presenting apparatus 100 is a center thereof. Alternatively, the detection-target region R may be a region in which a specific spot appointed by the user or the region detection part 104 is a center thereof.

The region detection part 104 further determines whether or not the mapping information included in the detection-target region R is a threshold or more. FIG. 5 is a diagram schematically showing the f(X,Y,Z)(t), which shows the mapping information on the position (X,Y,Z) at the time point (t).

The threshold is a particular value appointed by the user or a preset particular value. In FIGS. 5(a) and (b), in a case that the threshold is 0, a region of f(X,Y,Z) (t)≥0 shown by the hatching is a region of the mapping information that is more than the threshold.

FIG. 6 is a diagram schematically showing the detection-target region R and the mapping information. As shown in FIG. 6, the region detection part 104 determines whether or not the mapping information in the detection-target region R is the threshold or more, that is, the mapping information in the detection-target region R satisfies a condition of f(X,Y,Z) (t)≥0. The region detection part 104 supplies a determination result to the haptic-feedback arithmetic part 105.

The haptic-feedback arithmetic part 105 calculates a haptic feedback to be presented to the user on the basis of the determination result from the region detection part 104, and controls the haptic-feedback presenting part 106 to present the calculated haptic feedback.

Specifically, the haptic-feedback arithmetic part 105 presents the haptic feedback to the user in a case that the mapping information included in the detection-target region R is the threshold or more, and is capable of presenting no haptic feedback to the user in a case that the mapping information included in the detection-target region R is less than the threshold.

Moreover, the haptic-feedback arithmetic part 105 may calculate the haptic feedback depending on a size of the mapping information in the detection-target region R or the like. Specifically, the haptic-feedback arithmetic part 105 may intensify the haptic feedback when the mapping information in the detection-target region R is sufficiently more than the threshold, and may weaken the haptic feedback in a case that the mapping information in the detection-target region R is close to the threshold. An intensity of the haptic feedback may be adjusted by an oscillation intensity, an oscillation direction, a frequency, an oscillation pattern, or the like of the haptic-feedback presenting part 106.

The haptic-feedback presenting part 106 presents the haptic feedback calculated by the haptic-feedback arithmetic part 105 to the user. The haptic-feedback presenting part 106 may be a haptic-feedback presenting device (See WO/2015/151380) capable of causing the user to feel (haptic feedback) that the haptic-feedback presenting apparatus 100 is pulled in a particular direction. Moreover, the haptic-feedback presenting part 106 may be an eccentric motor producing an oscillation by rotation or a linear actuator producing an oscillation by translation. Furthermore, the haptic-feedback presenting part 106 may be capable of presenting the haptic feedback to the user.

The haptic-feedback arithmetic part 105 may calculate a direction in which the haptic feedback is presented depending on a direction of the mapping information with respect to the haptic-feedback presenting apparatus 100. As shown by an arrow in FIG. 6, the haptic-feedback arithmetic part 105 may, for example, present the direction of the mapping information that is the threshold or more in the detection-target region R to the user by the haptic feedback. Moreover, the haptic-feedback arithmetic part 105 may present a direction different from the direction of the mapping information that is the threshold or more in the detection-target region R to the user by the haptic feedback on the basis of the direction of the mapping information that is the threshold or more in the detection-target region R. For example, the haptic-feedback arithmetic part 105 may present a direction opposite to the mapping information that is the threshold or more in the detection-target region R to the user.

Operation of Haptic-feedback Presenting Apparatus

An operation of the haptic-feedback presenting apparatus 100 will be described. FIG. 7 is a flowchart showing the operation of the haptic-feedback presenting apparatus 100.

As shown in FIG. 7, the haptic-feedback presenting apparatus 100 starts the operation thereof, and the mapping-information acquisition part 101 acquires the mapping information f(X,Y,Z)(t) (St101).

Subsequently, the position detection part 102 and the attitude detection part 103 detect the attitude position (x,y,z,θ)(t) of the haptic-feedback presenting apparatus 100 (St102).

Subsequently, the region detection part 104 performs region detection (St103). In the case that the mapping information included in the detection-target region R is the threshold or more (St103: Yes), the haptic-feedback arithmetic part 105 calculates the haptic feedback to be presented to the user (St104), and makes the haptic-feedback presenting part 106 present the haptic feedback (St105). In the case that the mapping information included in the detection-target region R is less than the threshold (St103: No), the haptic-feedback arithmetic part 105 determines no haptic feedback to be presented to the user.

The haptic-feedback arithmetic part 105 may calculate the haptic feedback depending on the size of the mapping information included in the detection-target region R. The haptic-feedback arithmetic part 105 may, for example, intensify the haptic feedback gradually in a case that the size of the mapping information included in the detection-target region R is larger as the detection-target region R moves, and may weaken the haptic feedback in a case that the size of the mapping information included in the detection-target region R is smaller as the detection-target region R moves.

The haptic-feedback presenting apparatus 100 repeats the processing at the time point (t+n) after n seconds from the time point (t). The haptic-feedback presenting apparatus 100 operates as described above.

FIG. 8 is a diagram schematically showing an operation example of the haptic-feedback presenting apparatus 100. As shown in FIG. 8, at the time point (t), the mapping information f (X,Y,Z) (t) is outside the detection-target region R, and the value thereof is small. As a result, the haptic-feedback arithmetic part 105 determines no haptic feedback to be presented.

At the time point (t+n), the user and the haptic-feedback presenting apparatus 100 move, and the mapping information f (X,Y,Z) (t+n) is inside the detection-target region R and more than the threshold. As a result, the haptic-feedback arithmetic part 105 calculates the haptic feedback, and the haptic-feedback presenting part 106 presents the haptic feedback.

Moreover, the mapping information is increased between the time point (t) and the time point (t+n), and the haptic-feedback arithmetic part 105 may intensify the haptic feedback gradually. Furthermore, the haptic-feedback arithmetic part 105 may also add the attitude (θ) of the haptic-feedback presenting apparatus 100 to haptic-feedback calculation. For example, the haptic-feedback arithmetic part 105 may present the haptic feedback that the user moves in a direction opposite to a moving direction of the user in a case that the mapping information is increased with respect to the moving direction of the user.

The haptic-feedback presenting apparatus 100 operates as described above. As described above, the mapping information is presented to the user by the haptic feedback, and as a result, the user may grasp the mapping information without vision and audition.

Note that, as described above, attitude detection by the attitude detection part 103 may be performed at the same time as position detection. Alternatively, after it is determined that the mapping information included in the detection-target region R is the threshold or more (St103: Yes), the attitude detection by the attitude detection part 103 may be performed before the haptic-feedback calculation (St104).

About Navigation

FIG. 9 is a diagram schematically showing an example of navigation by haptic-feedback presentation. It is assumed that the navigation from the A spot to the B spot is performed such that it is avoided that the mapping information in the detection-target region R is the threshold or more (f(X,Y,Z)(t)≥0), in a case that the mapping information on the position (X,Y,Z) at the time point (t) is the f (X,Y,Z) (t), and the attitude position of the haptic-feedback presenting apparatus 100 at the time point (t) is the (x,y,z,θ)(t).

In FIG. 9, the black arrows show directions in which the mapping information is the threshold or more with respect to the haptic-feedback presenting apparatus 100, and the white arrows show directions (navigation directions) of the haptic feedback presented by the haptic-feedback presenting part 106.

At the time point (t0), the mapping information in the detection-target region R is less than the threshold, and the direction (white arrow) from the A spot to the B spot is calculated by the haptic-feedback arithmetic part 105.

At the time point (t1), the mapping information in the detection-target region R is the threshold or more, and the direction (white arrow) in which it is avoided that the mapping information is the threshold or more is calculated by the haptic-feedback arithmetic part 105. The direction (white arrow) in which it is avoided that the mapping information is the threshold or more is, for example, a direction different from the direction (black arrow) in which the mapping information is the threshold or more by a predetermined angle or more.

Similarly at the time point (t2) to the time point (t4), adding information of the B spot that is a destination, the directions (white arrows) in which it is avoided that the mapping information is the threshold or more are calculated by the haptic-feedback arithmetic part 105. In this manner, at the time point (t5), the haptic-feedback presenting apparatus 100 and the user reach the B spot. Although there is a region in which the mapping information is the threshold or more between the A spot and the B spot, it is possible that the user is guided avoiding the region.

About Plurality of Types of Mapping Information

The haptic-feedback presenting apparatus 100 is capable of supporting the plurality of types of mapping information. FIG. 10 is a diagram schematically showing the two types of mapping information and the detection-target region R. The mapping information A is, for example, an ultraviolet-ray amount, and the mapping information B is, for example, a scattered pollen count.

As shown in FIG. 10(a), at the time point (t), the mapping information A in the detection-target region R is the threshold or more (fa (X,Y,Z) (t)≥0), and the haptic-feedback presentation by the haptic-feedback presenting part 106 is performed.

After that, the haptic-feedback presenting apparatus 100 moves, and as shown in FIG. 10(b), at the time point (t+n), the mapping information B in the detection-target region R is the threshold or more (fb (X,Y,Z) (t+n)≥0). As a result, the haptic feedback presentation by the haptic-feedback presenting part 106 is performed.

The haptic-feedback arithmetic part 105 may calculate the different haptic feedbacks with respect to the mapping information A and the mapping information B respectively, and may make the haptic-feedback presenting part 106 present the different haptic feedbacks. The different haptic feedbacks are, for example, a haptic feedback having a low frequency with respect to the mapping information A, and a haptic feedback having a high frequency with respect to the mapping information B. Due to this, the user may grasp the type of the mapping information by a type of the haptic feedback.

For example, in a case that the mapping information A is the ultraviolet-ray amount, and the mapping information B is the scattered pollen count, the user may recognize that the ultraviolet-ray amount is the threshold or more by the presented haptic feedback having the low frequency. After that, the user may recognize that the scattered pollen count is also the threshold or more by the presented haptic feedback having the high frequency. Note that the number of the types of the mapping information is not limited to two, and may be three or more.

Method of Detecting Mapping Information

As described above, the mapping-information acquisition part 101 may acquire the mapping information from cloud information and an output from a sensor. As various methods of detecting the mapping information, an radio wave intensity as an example of the density of an environment may be measured by a measurement method in which an electromagnetic field is used, and an scattered pollen count and a scattered dust count as examples of the density of an environment may be measured by a measurement method in which a scattered light intensity and a degree of polarization are used.

Moreover, precipitation may be measured by a measurement method in which capacitance is detected, and photocoupler penetration is used, and radiation dose may be measured by a Geiger-Mueller counter, a scintillation counter, or a PIN photodiode. Quantity of airflow may be measured by a measurement method in which an airflow meter is used.

Congestion in a train and a running position as examples of the density of a thing may be acquired from official information from each railway company, a user submission, or the like. Crowding of human, a place, and the like as examples of the density of human may be acquired from a user submission, a submission limited to a particular user by ID registration, or the like.

Exaltation and a calm as examples of the density of a feeling may be detected by sensing a human body state by using an electroencephalogram, cooperation with a wearable heart rate, or the like.

The mapping information is not limited to the information described above, and may be information related to a particular position in space or on a plane. Moreover, the mapping-information acquisition part 101 may generate the mapping information depending on appointment by the user or the like.
